Trial Outcomes & Findings for An Asian Study to Assess the Properties and Profile of Ticagrelor in Patients With Stable Coronary Artery Disease (NCT NCT01118325)

NCT ID: NCT01118325

Last Updated: 2014-07-08

Results Overview

Final extent IPA from pre-dose baseline was calculated using the following formula for Adenosine Diphosphate (ADP)-induced platelet aggregation: Percentage Inhibition = 100% x (PAs - PA) / (PAs) Platelet Aggregation (PA) was the mean response at the given post dose time point and PAs was the mean response at pre dose baseline. Percentage inhibition was restricted to the closed interval \[0,100\]; any data falling outside this range was truncated to the appropriate limit.

Participant Flow

In total, 146 patients were enrolled at 15 sites from 2 countries (Japan and Philippines). The study period was from April 2010 to March 2011. In total, 139 subjects were randomised and received the investigational product. Most subjects completed the study but 2 Japanese patients discontinued due to an AE during the 4 weeks treatment period.

PRIMARY outcome

Timeframe: Week 4

Population: Only Japanese participants who had IPA data at Week 4 were considered in this analysis. Arm AZD6140 90 mg bd includes one non-Japanese participant resident in Japan

Final extent IPA from pre-dose baseline was calculated using the following formula for Adenosine Diphosphate (ADP)-induced platelet aggregation: Percentage Inhibition = 100% x (PAs - PA) / (PAs) Platelet Aggregation (PA) was the mean response at the given post dose time point and PAs was the mean response at pre dose baseline. Percentage inhibition was restricted to the closed interval \[0,100\]; any data falling outside this range was truncated to the appropriate limit.
